Biodiversity Beyond National Jurisdiction Bill

James Naish Excerpts

2nd reading
Thursday 16th October 2025 Commons Chamber

[Sarah Champion (Rotherham) (Lab)]

I am really proud to be standing here today, because it is an historic day for ocean conservation. Let us make no mistake: the world’s oceans are under significant threat. The Intergovernmental Panel on Climate Change estimates that if global warming reaches 1.5°, 70% of coral reefs will die. If temperatures rise by 2°, as now sadly looks likely, 99% of the Earth’s coral reefs will die. Coral reefs are not just a pretty thing that we go diving on; they are incredibly complex and important ecosystems. They are fish nurseries, but they also provide significant protection for islanders from both adverse weather and sea level rises.

Other threats include illegal, unreported and unregulated fishing, which is decimating fish populations across the globe, and deep-sea mining, which threatens to cause damage from which ecosystems will take decades to recover. Currently, two thirds of the ocean lie outside the jurisdiction of national states, and that is what the Bill focuses on. For the health of oceans and the planet as a whole, it is crucial that the international community develops ways of ensuring that these areas are not subject to lawless exploitation, as is currently happening.

In January this year, as Chair of the International Development Committee, my hon. Friend wrote to the Government to push them to ratify the global oceans treaty. As a member of her Committee, I thank her for her efforts on this front. If I recall correctly, our Committee’s work highlighted that the UK had to work globally because there are 3 billion people who depend on the oceans for work, especially in poorer, smaller developing nations. Does she agree that this is a vital step forward for the future, especially of small island developing states, and that the Government must push others who have signed up to this treaty to ratify it?

I thank my hon. Friend and colleague. He is absolutely right, and that is why today is so historic: this is the UK taking that leadership role and hopefully corralling some of the other countries that are more reticent to do the right thing.

The International Development Committee and the all-party parliamentary group for the ocean, both of which I chair, have long been calling on both the previous Government and this Government to put in place the necessary legislation to ratify this agreement. To have finally reached this point is a credit to the Ministers—particularly the Minister for Water and Flooding, my hon. Friend the Member for Kingston upon Hull West and Haltemprice (Emma Hardy), but also the Minister responsible for the Indo-Pacific, my hon. Friend the Member for Feltham and Heston (Seema Malhotra), and the Minister of State for International Development and Africa, my noble Friend Baroness Chapman.

In an era of international fragmentation, I am relieved that 145 states have come together to forge this agreement and safeguard a global public good. As my hon. Friend the Member for Rushcliffe (James Naish) alluded to, 75 countries have already taken the next step of ratification. I am very proud that the Minister for Water and Flooding was championing this in opposition and has delivered on her word, leading this ratification in government. I thank her for that.

As a seafaring nation and a centre of expertise in maritime law, the UK is perfectly placed to lead the charge to protect the world’s oceans. Sadly, we are lagging behind many countries, including the Seychelles, St Lucia and Barbados, which ratified the agreement last year. It is not surprising that the small island developing states, or SIDs—or large ocean states, as they prefer to be called—were quick to ratify, because they recognise the existential threat that ocean ecosystem degradation poses to human societies and their economies.

As the International Development Committee argued in our report last year, SIDs need reliable partners. The UK talks a good game when it comes to responsible global leadership, but activists and policymakers from SIDs told the Committee they were concerned about the consistency of Britain’s commitment. I hope we will see that change at this moment, under this Government, and that we will stand up for small island developing states, particularly our overseas territories, which the hon. Member for Romford (Andrew Rosindell) mentioned.

The health of the world’s oceans is not an issue confined to low-income countries; it is an existential issue for all of us. As the Government’s impact assessment acknowledged, the impact of reduced fish stocks and decreased capacity will be borne by all of us, including future generations. The UK must seize this moment to match its international conservation ambitions with tangible action to protect our domestic waters. Bottom trawl fishing, a highly destructive practice, is still permitted across almost all of the UK’s seas, including in more than 90% of our marine protected areas. I welcome the Government’s consultation on that, and hope that they will take the necessary step to ban that practice wherever they can.

The Government must consider introducing additional legislation to ensure that the UK’s marine protected areas are actually protected, because sadly, even though they have the title, many of them are not. The Bill also offers plentiful opportunities for the UK’s blue economy as a world leader in marine science and technologies. To support quick progress, the UK needs a definition of the use of “marine genetic resources”, and “digital sequence information”, by the time the agreement is ratified. That is to support all those who will implement it.

The UK’s next steps are vital to ensure that we fulfil our leadership role in ocean protection. The 120-day countdown has started. The first conference of the parties, Ocean COP1, will be held within just 12 months. With the clock ticking, will the Minister set out a timetable for the passage of the Bill through both Houses? We need it to pass quickly to allow the UK to play its full part in the first conference. Will the Minister also confirm whether the Bill legally extends the UK’s existing domestic duties to have regard to the precautionary and polluter pays principles to the high seas? If not, will she say whether something to that effect should or could be inserted into the Bill? Will the Minister consider producing an ocean strategy? Ocean issues currently fall between a number of different Departments, which unfortunately means they are under the ownership of none. The Bill is to be commended and must attain Royal Assent without delay. I strongly urge all Members to support it.
